fs: dlm: handle sequence numbers as atomic
Currently seq_next is only be read on the receive side which processed in an ordered way. The seq_send is being protected by locks. To being able to read the seq_next value on send side as well we convert it to an atomic_t value. The atomic_cmpxchg() is probably not necessary, however the atomic_inc() depends on a if coniditional and this should be handled in an atomic context.
